IS: 2878 -1986

( Second Revision )0. FOREWORD 0.1 This Indian Standard ( Second Revision)was adopted by the Indian Standards Institution on 29 August 1986, after the draft finalized by the Fire Fighting Sectional Committee had been approved by the Civil Engineering Division Council. 0.2 One of important types of fire extinguishers used for putting out fire is the carbon dioxidetype which is suitable for fire fighting in oils, petroleum products and gas substances under pressure ( Classes B and C tires ) and also for fires involving electrical equipment. This standard was first published in 1964 and revised in 1976. This revision is being prepared so as to include higher capacity of fire extinguishers ( requiring the use of trolley ) besides up-dating the requirements in respect of the materials. 0.3 For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS : 2-1960*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.-

IS : 2878 - 1986 2.2 The capacity of the extinguisher shall be the mass of carbon dioxide when it is filled in the container to the filling ratio as in 4.1. 3. MATERIAL 3.1 The material for construction Table 1.TABLE 1 MATERIALS SL No. COMPONENT

The extinguisher shall be cleaned internally and shall be filled with liquefied carbon dioxide to the filling ratio of not more than 0667. The quantity The filling ratio is the ratio of mass shall be determined by weighing. of liquefiable gas in the container to the mass of water required to fill the container at 15C.*Specification for carbon dioxide ( second revisfon )..

The Standard Mark on products covered by an Indian Standard conveys the assurance that they have been produced to comply with the requirements of that standard under a well defined system of inspection, testing and quality control which is devised and supervised by BlS and operated by the producer. Standard marked products are also continuously checked by BIS for conformity Details of conditions under which a to that standard as a further safeguard. licence for the use of the Standard Mark may be granted to manufacturers or producers may be obtained from the Bureau of Indian Standards.

APPENDIX ( Clause 9.1 )

SAMPLING A-O. GENERAL AND CRITERIA FOR

A,CONFORMITY

A-0.1 The risk involved in failure of a fire extinguisher to work, when needed, is extremely large. Fire extinguisher, therefore, ought to have a high degree of reliability for performance during the entire specified period of its service. It can be achieved only ,through adequate design and control of quality of all raw materials, component parts and fittings followed by process con:rol in all stages of manufacture and assembly. A-l. SAMPLlNG

A-l.1 All fire extinguishers of the same type,, shape, design and capacity produced by the same manufacturer from similar materials

I!S : 2871- 1986 under almost identical conditions of manufacture shall be grouped together to constitute a lot. A-l.2 Each lot shall be considered individually for the purpose of evaluation of quality in accordance with this specification. A-1.2.1 The number of samples for testing to be taken at random from a lot_ and the criteria for conformity shall be as given in A-1.2.2. A-1.2.2 From each lot, a number of samples as indicated below be selected at random. Number of Items in the Lot up to 25 26 to 50 51 to 100 101 and up to 200 Sample Size 3 5 8 8 percent shall

A-1.2.3 They shall be examined visually, as far as possible, in respect of requirement specified in 2 to 6 and 8 and in respect of leakage test _ ( see 7.3 ). A-1.2.4 All the samples tested shall pass all these tests for the lot to be declared to conform to these requirements. A-1.2.5 One sample shall then be examined for discharge duration and one for intermittent operation and one of these for leakage. A-1.2.6 In the absence of a test certificate from a manufacturer about conformity of various components ( see 3 ) and the quality of charge ( see 4 ) to the requirements of this specification, from a sample fire extinguisher one item each of all the component parts and fittings shall be taken separately and examined individually in respect of the relevant requirements laid down in this specification. The sample shall also meet the requirements regarding the quality of charge ( see 4 ).

AMENDMENT NO. 3 MARCH 2002 TO IS 2878:1986 SPECIFICATION FOR FIRE EXTINGUISHER, CARBON DIOXIDE TYPE (PORTABLE AND TROLLEY MOUNTED)(Second Reviswn )( Foreword) Insert the following new clause after 0.2 and renumber the

subsequent clause 0.3 A scheme for labelling environment friendly products known as ECO Mark has been introduced at the instance of the Ministry of Environment and Forests (MEF), Government of India. The ECO Mark would be administered by-the Bureau of Indian Standards (BIS) under the EN Act, 1986 as per the Resolution No. 71 dated 21 February 1991 and No. 425 dated 28 October 1992 published in the Gazette of the Government of India. For a product to be eligible for marking with ECO logo, it shall also carry the 1S1Mark of BIS besides meeting additional optional environment friendly requirements. For this purpose, the Standard Mark of BIS would be a single mark being a combination of the 1S1Mark and the ECO logo. Requirements to be satisfied for a product to qualify for the BIS Standard Mark for ECO friendliness being included in the relevant published These requirements are optional; standards through an amendment. manufacturing units are free to opt for the 1S1Mark alone also. The amendment is based on the Gazette Notification No. 160 dated 1 April 1999 for Fire Extinguishers as environment friendly products published in the Gazette of Government of India. ( Page 7, clause 7.3 ) Insert the following new clauses after 7.3 and renumber the subsequent clauses: 8 OPTIONAL REQUIREMENTS 8.1 General Requirements8.1.1 Any tire extinguisher having BIS Standard Mark qualifies for consideration of ECO Mark. 8.1.2 The products manufacturer must produce the consent clearance as per provision of the Water (Prevention and Control of Pollution) Act, 1974, Water (Prevention and Control of Pollutwn) Cess Act, 1977 and Air (Prevention &
